Definitions

  • This invention relates to 4-(hydroxymethyl)-2,3,5,6-tetrafluorobenzyl esters useful in combating insects and similar invertebrate pests, to processes for their preparation, to compositions comprising them, and to methods of using them to combat and knock down insects and similar invertebrate pests.
  • this and other esters of 4-(hydroxymethyl)-2,3,5,6-tetrafluorobenzyl alcohol, and compositions comprising them exhibit high levels of contact, residual and fumigant insecticidal activity, characterised by exceptionally high levels of knockdown effect, particularly against cockroach species such as Blattella germanica .
  • knockdown is meant a rapid immobilisation of the affected insect resulting from an induced incapacity for coordinated movement such as flight or walking.
  • This enhanced knockdown effect would not have been suspected from such a close analogue of tefluthrin, which is characterised by a high level of intrinsic activity against soil-dwelling pests, and which does not rely on knockdown for effective control thereof.
  • the invention provides an insecticidal composition, comprising an insecticidally effective amount of a compound of formula (I) : wherein X represents a group of formula : where either (i) R1 and R2 are each selected from hydrogen, halo and alkyl of up to four carbon atoms, or (ii) R1 is hydrogen and R2 represents either a group of formula : or a group of formula : where R3 and R4 are each selected from hydrogen, methyl, halo and haloalkyl of one or two carbon atoms containing at least two fluorine atoms, and R5 is selected from chloro and bromo, or a stereoisomer thereof, in combination with an insecticidally inert carrier or diluent.
  • X represents a group of formula : where either (i) R1 and R2 are each selected from hydrogen, halo and alkyl of up to four carbon atoms, or (ii) R1 is hydrogen and R2 represents either a group of formula :
  • the invention provides a method of combating insect pests at a locus in which an insecticidally effective amount of a composition as hereinbefore described is applied to the locus.
  • the invention provides a composition for causing knockdown of insect pests comprising an amount of a compound of formula (I), or a stereoisomer thereof, wherein X, R1, R2, R3, R4 and R5 have any of the meanings given hereinbefore, which is effective in causing said knockdown in combination with an insecticidally inert carrier or diluent, and in a fourth aspect, the invention provides a method of combating insect pests at a locus in which an amount of a composition as hereinbefore described which is effective in causing knockdown of insect pests is applied to the locus.
  • the invention provides a novel compound of formula (I), or a stereoisomer thereof, wherein X, R1, R2, R3, R4 and R5 have any of the meanings given hereinbefore, with the proviso that X may not represent the group (1RS, cis )-3-(Z-2-chloro-3,3,3-trifluoroprop-1-en-1-yl)-2,2-dimethylcycloprop-1-yl.
  • the compounds according to formula (I) may exist in a number of stereoisomeric forms resulting from the nature of the group X.
  • X represents a substituted cyclopropane group
  • the carbon atom at the 1-position of the cyclopropane ring may be asymmetrically substituted and may exist in the R -form or the S -form.
  • the carbon atom at the 3-position of the cyclopropane ring may also exist in the R -form or the S -form when the groups R1 and R2 are not identical; the presence of two such asymmetrically substituted centres in the cyclopropane ring is additionally characterised by the existence of cis and trans isomers, according to the relative configuration of the ring substituents.
  • the group R2 contains a carbon-carbon double bond, there exists the further possibility of E - and Z -isomeric forms.
  • isomeric forms of the compounds according to formula (I) exhibit different biological characteristics, for example differing levels of insecticidal or knockdown activity. All individual isomeric forms and mixtures thereof, including racemates, arising from stereoisomerism in the group X or elsewhere in the structure of compounds according to formula (I) are within the scope of the invention.
  • Preferred compounds according to the invention include the (IR) and racemic forms of those listed below:
  • Preferred compounds according to the invention also include :
  • the compounds of the invention are esters and may be prepared by conventional esterification processes, of which the following are examples :
  • the preparation of individual isomers may be carried out in the same manner but commencing from the corresponding individual isomers of compounds of formula (II). These may be obtained by conventional isomer separation techniques from mixtures of isomers. Thus cis and trans isomers may be separated by fractional crystallisation of the carboxylic acids or salts thereof, whilst the various optically active species may be obtained by fractional crystallisation of salts of the acids with optically active amines, followed by regeneration of the optically pure acid.
  • optically pure isomeric form of the acid may then be reacted with the alcohol of formula (III) or a halide, mesylate or tosylate of formula (IV) to produce a compound of formula (I) in the form of an individually pure isomer thereof.
  • halides of formula (IV) wherein Q1 represents chlorine or bromine may be prepared by monohalogenation of the alcohol of formula (III) according to the process described in UK patent application number 2153819A.
  • the alcohol of formula (III) may itself be prepared by the processes described in Scheme I.
  • the compounds of formula (I) may be used to combat and control infestations of insect and acarine pests.
  • the insect and acarine pests which may be combated and controlled by the use of the invention compounds include those pests associated with agriculture (which term includes the growing of crops for food and fibre products, horticulture and animal husbandry), forestry, the storage of products of vegetable origin, such as fruit, grain and timber, and also those pests associated with the transmission of diseases of man and animals.
  • compositions which include in addition to the insecticidally active ingredient or ingredients of formula (I) suitable inert diluent or carrier materials, and/or surface active agents.
  • the compounds of the invention may be the sole active ingredient of the composition or they may be admixed with one or more additional active ingredients such as insecticides, insecticide synergist, herbicides, fungicides or plant growth regulators where appropriate.
  • Suitable additional active ingredients for inclusion in admixture with the compounds of the invention may be compounds which will broaden the spectrum of activity of the compounds of the invention or increase their persistence in the location of the pest. They may synergise the activity of the compounds of the invention or complement the activity for example by increasing the speed of effect, improving kill or knockdown of target insect pests, or overcoming repellency. Additionally multi-component mixtures of this type may help to overcome or prevent the development of resistance to individual components.
  • insecticide herbicide or fungicide included in the mixture will depend upon its intended utility and the type of complementary action required.
  • suitable insecticides include the following :
  • insecticides having particular targets may be employed in the mixture if appropriate for the intended utility of the mixture.
  • selective insecticides for particular crops for example stemborer specific insecticides for use in rice such as cartap or buprofezin, can be employed.
  • insecticides or acaricides specific for particular insect species/stages for example ovolarvicides such as clofentezine, amitraz, chlordimeform, flubenzimine, hexythiazox and tetradifon, motilicides such as dicofol or propargite, adulticides such as bromopropylate, chlorobenzilate, or insect growth regulators such as hydramethylnon, cyromazine, methoprene, chlorfluazuron and diflubenzuron may also be included in the compositions.

  • suitable insecticide synergists for use in the compositions include piperonyl butoxide, sesamex, and dodecyl imidazole.
  • Suitable herbicides, fungicides and plant growth regulators for inclusion in the compositions will depend upon the intended target and the effect required.
  • An example of a rice selective herbicide which can be included is propanil, an example of a plant growth regulator for use in cotton is "Pix", and examples of fungicides for use in rice include blasticides such as blasticidin-S.
  • the choice of other ingredients to be used in mixture with the active ingredient will often be within the normal skill of the formulator, and will be made from known alternatives depending upon the total effect to be achieved.
  • the ratio of the compound of the invention to any other active ingredient in the composition will depend upon a number of factors including the type of insect pests to be controlled, and the effects required from the mixture. However in general, the additional active ingredient of the composition will be applied at about the rate it would usually be employed if used on its own, or at a lower rate if synergism occurs.
  • compositions may be in the form of dusting powders wherein the active ingredient is mixed with a solid diluent or carrier, for example kaolin, bentonite, kieselguhr, or talc, or they may be in the form of granules, wherein the active ingredient is absorbed in a porous granular material, for example pumice.
